Implications of Vdroop for overclocking?

[AD-15]

hello,

I'm looking at purchasing the Gigabyte EX58 UD5 (I'm assuming it's an ideal choice for overclockers?); and having done some research on the internet it seems this board has a more considerable issue with vdroop than the other rival boards.

Obviously, for normal operation, this is no problem. However, I do intend to OC an i7 920 DO on this board as much as I can (aiming for the 4GHz CPU clock mark/200 Mhz Bclck). What possible implications will the vdroop have on the stability of the system at these speeds?

I understand you can simply counter-act the drop in voltage by increasing the starting voltage to begin with. But would this result in higher temperatures when the chip is idle? Also, would there be any other effects as a result of vdroop, other than the unstability caused by drop in voltage?

I've heard Load Line Calibration can improve (reduce) the vdroop effect, would LLC in any way impact overclocking either?

Thanks!

The UD5 is a great board. vdroop will just mean you need slightly higher voltage, nothing major though tbh. As you're aiming for 4GHz you will hardly see a difference

I understand you can simply counter-act the drop in voltage by increasing the starting voltage to begin with.

Vdroop is actually caused by following Intels standards. There are better ways to make sure the voltage to the chip (such as LLC that you mentioned) stays a bit more constant.

The UD4 has LLC (using it at the moment - great board) : http://forums.vr-zone.com/overclocki...4-testing.html

No vdroop happen, after enable LLC in BIOS.

Check out the pics + details on that page. I'd be very surprised if the UD5 didn't give the same results.
